INKING- ARRANGEMENT FOR PRINTING-PRESSES.

To all whom it may concern: I

Be it known that I, GEORGE P. FENNER, a citizen of the United States, residing at New London, in the county of New London and State of Connecticut, have invented new and useful Improvements in Inking Arrangements for Printing-Presses, of which the following is a specification.

This invention relates to means by which the vibration of ink rollers can be regulated or entirely stopped.

This invention is set forth in the following specification and claim and illustrated in the annexed drawing, in which Figure l is the side elevation of an inking arrangement embodying this invention. Fig. 2 is a plan view of Fig 1. Fig. 3 is an end view of Fig. 1. p

In this-drawing is shown a car a for rotating the ink rollers and a fort b engaging a spool c and actuated by a nut d to vibrate the ink roller. There are two nuts (1 shown in the drawin but theexplanation of one also explains t e other.

Each nut d is connected by a link 6 to a casting orlever piece 1" having a fulcrum or ivot on a bracket or arm f. The nut d by ink e engages and vibrates the lever piece 1' and by pivot g and link 7?, this vibration is conveyed to fork b and spool c and thence to ink roller 76. The rack m rotating gear a also imparts the regzuired rotation to screw 12 actuating the nut The spool c as also gear 0 are on the shaft of the vibrating roller is.

In Fig. 2 'at the left the pivot connection- 9 is shown at a distance from the fulcrum point'of lever r, on bracket f, while at the right the pivot g is shown set over or to coincide or register with the pivot or fulcrum oint of the lever r. i As the connection it or 1ts pivot g is set to one extreme or another the vibration .of the roller 7c can be varied from a considerable extent down to nothing or entirely eliminated. The levers r are shown independent of one another and at each Specification of Letters Patent. Application filed August 16. 1907. Serial No. 388.899.

lever the adjustment can be made for a respective vibration of roller as desired.

I do not claim anything set forth in U. S. Patent 818,238, granted April 17, 1906, for inking arrangement for printing presses.

The reason forstopping this vibration altogether is: because there is, sometimes, more than one color of ink in the ink fountain. This fountain has partitions, in which case, the endwise motion of the vibration of the steel rollers would tend to work thesedifferent colors of ink altogether. If the vibration is stopped, this tendency is cured.

Now what I claim is: g 1. A device for regulating the vibration of an ink roller which comprises a vibrator nut or screw,-a lever piece vibrated by the nut and a link for conveying motion from the lever piece to the roller, said link being adjustable to coincide with the fulcrum of the lever to eliminate vibration.

2. A device for regulating the vibration of an ink roller which comprises a vibrator nut or screw, a slotted lever actuated by the nut, and a link for connecting the lever and roller, said link having its connection adjustable along the slot of the lever to coincide with or be out of register with the fulcrum.

- 3. A device for regulating the vibration of i an ink roller which com rises a vibrator nut or screw, a lever piece vibrated by the nut, a fixed bracket, a fulcrum for the lever supported on the bracket, and a link for conveying motion from the lever piece to the roller, said. link being adjustable to coincide with the fulcrum of the lever to eliminate vibration.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

GEO. P. FENNER.
